The moving direction of the clamping conveying device is Y direction, and the moving direction of the upper processing machine head is X direction. Because the clamping conveying device only clamps one side of the plate, the plate possibly tilts at the position deviated from the clamping conveying device, and the tilted part floats during processing, so that the quality of the processed holes and grooves is uneven. In this regard, the upper processing machine head can be additionally provided with a set of pressing plate device, and the pressing plate device compresses the plate when the upper processing machine head processes holes or grooves, so that the plate is tightly attached to the platform, and the processing quality is ensured.

However, when the production process finds that when the part of the upper processing machine head, which needs to process the plate, is relatively close to the clamping and conveying device, the pressing plate device collides with the clamping and conveying device when pressing the plate downwards, so that the plate cannot be pressed downwards normally, if the pressing plate device is abandoned to be used for pressing the plate, the plate can be tilted, the processing quality is affected, and the plate is trapped into the selection. In addition, in order to achieve dust-free processing, the platen device is usually connected to a dust-collecting device. The existing upper machining machine head uses an angle head to draw grooves or drill holes on the side face of a plate, a plurality of openings are formed in the pressing plate device for compatibility of the angle head, and when the angle head is replaced by a single head, the upper machining machine head is not ideal in dust collection effect of the dust collection device due to the existence of the openings.

The six-sided drilling and milling machining center 100 of the present invention includes a frame 10, a machining table 20, a clamping and conveying device 30, an upper machining head 40, and a lower machining head 50. The processing table 20 is mounted to the frame 10, and the frame 10 is formed with a cross member 11 arranged in the left-right direction above the processing table 20. The upper machining head 40 is mounted to the cross member 11 so as to slide left and right. The clamping and conveying device 30 is mounted to the frame 10, and the clamping and conveying device 30 is used for clamping the plate material and conveying the clamped plate material along the front-rear direction. The lower processing head 50 is mounted below the processing tool 20. The upper processing head 40 is used for processing the other side surfaces of the plate except the bottom surface, and the lower processing head 50 is used for processing the bottom surface of the plate. During processing, the clamping and conveying device 30 clamps and then conveys the plate backwards, and conveys the plate to the lower part of the upper processing machine head 40, and the upper processing machine head 40 and the lower processing machine head 50 process each side surface of the plate. The clamping and conveying device 30 clamps the left side of the plate and positions the plate.

As shown in fig. 2, the direction indicated by the arrow Y is the front-to-back direction, the direction indicated by the arrow X is the left-to-right direction, and the direction indicated by the arrow Z is the bottom-to-top direction.

As shown in fig. 3 to 9, the upper machining head 40 of the present invention includes a support frame 41, an upper machining spindle 42, a first driver 43, a first platen 44, and a second platen 45. The lower end of the upper machining spindle 42 is a spindle end 421. The upper processing spindle 42 is mounted to the support frame 41 so as to be vertically slidable. The first driver 43 is mounted on the support 41, the upper machining spindle 42 is mounted on an output end of the first driver 43, and the first driver 43 drives the upper machining spindle 42 to move up and down. The second pressing plate 45 is sleeved on the spindle end 421, and the first pressing plate 44 is disposed around the spindle end 421. The first platen 44 is disposed to be movable up and down, the first platen 44 having a first retracted position above and a first depressed position below. The second platen 45 is disposed so as to be movable up and down, and the second platen 45 has a second avoidance position located above and a second depression position located below. The first platen 44 in the first depressed position and the second platen 45 in the second depressed position are flush, and the first platen 44 encloses the second platen 45.

During processing, the first pressing plate 44 is moved to the first pressing position, the second pressing plate 45 is moved to the second pressing position, and at this time, the first pressing plate 44 and the second pressing plate 45 are pressed downwards together to press the plate material, and at this time, the plate material is sufficiently positioned. As shown in fig. 13 and 14, the first pressing plate 44 in the first avoiding position is located above the second pressing plate 45 in the second pressing position, when the second pressing plate 45 presses the plate, the first pressing plate 44 is located above the second pressing plate 45, the first pressing plate 44 is lifted upwards, the first pressing plate 44 is also located above the clamping and conveying device 30, and the first pressing plate 44 does not interfere with the clamping and conveying device 30, so that the upper machining spindle 42 can move to a position closer to the clamping and conveying device 30, and the machining range of the upper machining spindle 42 is effectively increased. As shown in fig. 16, which is a simple structure schematic diagram of a six-sided drilling and milling machining center in the prior art, when a machining part is required to be relatively close to the clamping and conveying device 03, the pressing plate device 02 is a whole and can only lift up and down integrally, and collides with the clamping and conveying device 03 when the pressing plate descends, movement interference occurs, and the interference part is shown as an arrow a part in fig. 16, which causes that the machining spindle 01 cannot normally perform slotting/drilling, if the pressing plate is not pressed, the positioning of the plate is insufficient, and the machining quality is difficult to ensure, so that the machining is difficult to select. Therefore, the upper machining head 40 has good machining flexibility, effectively increases the machining range of the upper machining main shaft 42, and is more flexible to use.

As shown in fig. 15, it is of course possible to compress the sheet material using only the first platen 44 according to actual needs, and the first platen 44 in the first depressed position is located above the second platen 45 in the second retracted position.

It should be noted that the upper processing spindle 42 may be of an existing structure, and a cutter is installed at the output end of the upper processing spindle 42, where the cutter is an angle head or a single head, and the angle head is used for processing a side surface of a plate, and the single head is used for processing a top surface of the plate.

As shown in fig. 3 to 9, it is preferable that the first platen 44 semi-encloses the spindle end 421, and the first platen 44 in the first pressing position semi-encloses the second platen 45 in the second pressing position, and the right end of the second platen 45 exceeds the first platen 44, in such a manner that arrangement of the first platen 44 and the second platen 45 is facilitated. Further, the second pressing plate 45 is connected to a dust hood 46, the second pressing plate 45 is provided with a mounting notch 451 for accommodating a cutter, and the mounting notch 451 is communicated with the dust hood 46. When the single head is mounted on the spindle end 421, the single head is positioned in the mounting notch 451, when the second pressing plate 45 is in the second pressing position to press the plate, negative pressure is generated in the dust hood 46, and the scraps generated during the single head processing flow to the dust hood 46 through the mounting notch 451 to extract the scraps generated during the processing. For the angle head, since the angle head is used as a side surface for processing the plate material, the second pressing plate 45 does not press the plate material when the angle head is processed, and dust cannot naturally flow to the suction hood 46 through the mounting gap 451, and the dust is collected by another collecting device.

Preferably, the mounting notch 451 includes a circular notch 4511 and a square notch 4512, the circular notch 4511 and the square notch 4512 being in communication, the circular notch 4511 and the square notch 4512 being in tandem.

In contrast, the pressing area of the first pressing plate 44 is about half that of the pressing plate device of the prior art, but since the second pressing plate 45 can also be a pressing plate, the pressing area of the first pressing plate 44 and the second pressing plate 45 is nearly equal to that of the pressing plate device of the prior art, and may be even larger.

For the blade of dodging the angle head, dodging the groove 444 that extends along left and right direction has been seted up to the bottom of left side pushing down structure 441, and dodging the groove 444 that extends along left and right direction has been seted up to the bottom of right side pushing down structure 442, and dodging the groove 444 that extends along the fore-and-aft direction has been seted up to the bottom of rear side pushing down structure 443, and the blade of angle head stretches into dodging the groove 444, plays and dodges the effect. To better compress the sheet. The bottoms of the left side pressing structure 441, the right side pressing structure 442, and the rear side pressing structure 443 are each mounted with a small pressing plate 445.

The second platen 45 is mounted at an output end of the third driver 48, and the third driver 48 drives the second platen 45 to move up and down, so that the second platen 45 is switched between a second pressing position and a second avoiding position. The upper machining spindle 42 is provided with 2 second drivers 47 connected to a left pressing structure 441 and a right pressing structure 442, respectively. The first driver 43 drives the upper machining spindle 42 up and down so that the spindle end 421 is far from or near the sheet material, allowing a single head or angle head to machine the sheet material. The first actuator 43, the second actuator 47 and the third actuator 48 are air cylinders, but other linear actuators may be used. In practical use, the upper machining spindle 42 is an electric spindle, and is mainly used for driving a single head or an angle head to mill grooves on the side surface of the plate.

As shown in fig. 3 and 4, the upper processing head 40 further includes an upper drill set device 49, the upper drill set device 49 is mounted to the support frame 41, and the upper drill set device 49 is used for drilling a side surface of the plate. The upper machining spindle 42 and the upper drill set device 49 are matched with each other to finish slot milling and drilling of the side face of the plate. In addition, the upper processing machine head 40 of the invention further comprises a mounting frame 401, the supporting frame 41 is arranged on the mounting frame 401 in a manner of being capable of sliding up and down, a driving motor 402 is arranged on the mounting frame 401, the output end of the driving motor 402 is connected with the supporting frame 41, and the driving motor 402 drives the supporting frame 41 to move up and down so as to drive the upper processing main shaft 42 and the upper drill set device 49 to move up and down, and the upper processing main shaft is close to or far away from a plate. The first driver 43 is used for driving the upper processing main shaft 42 to move up and down, driving the upper processing main shaft 42 to move downwards out of the upper drill set device 49, so that the upper processing main shaft 42 can conveniently perform groove milling on the side surface of the plate. The lifting cylinder 403 is further installed on the installation frame 401, the lifting cylinder 403 is connected with the supporting frame 41, and the lifting cylinder 403 lifts the supporting frame 41 to play a role of counterweight.

As shown in fig. 1, 2, 10, 11, and 12, the processing machine 20 includes a front table 21 and a rear table 22. The front table 21 and the rear table 22 are arranged in tandem, and a movement path 23 is formed between the front table 21 and the rear table 22. The front table 21 and the rear table 22 are translationally adjustable back and forth. The lower processing head 50 is provided directly below the movement path 23. The lower machining head 50 includes a first lower machining spindle 51 and a second lower machining spindle 52. The first lower machining spindle 51 and the second lower machining spindle 52 are arranged side by side in a side-by-side relationship.
